Hi Adam,
Have you considered a 2 IGBT version of your driver? I saw that others also asked about it before. I have a couple of questions about the driver board. What diodes are you using with the gate resistors? How did you make the pads for the IGBTs? Just 3 overlapping pads? Were the PCB house happy with that?
Starting to work through the control board, I have a question about the precharge circuit, how does it work? Are the FET and your contactor switching the positive side of the battery? It looks like it from CAP+ label. But how does the FET, Q8 gets switched on and off? The +15V supply is referenced to the negative of the pack (PE), or did I get it all wrong?
Thanks
John
